To all 'whom it may concern:

Be it known that I, (Julianne H. AmmaeoN, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in- WindowSash Construction; and I do llereby declare the following to be a full, clear, and exactdescription of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sash structures,-more particularly to such as are employed for car windows,and the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims h In the accompanying drawings- Figure 1 is a view in elevation partl bro en away, of one embodiment of m invention; Fig. 2 is a. view showing one o the upper corner brackets and its connection with the right hand sash rail in section; the ed e portions of lower right hand corner brac et and its connection with the rail being shown in elevation' Fig. 3 is a longitudinal sectional view through the lower right hand corner bracket containing the locking device; Fig. 4 is an inside view of the same corner bracket; Fi 5 1s a sectional view on the line 5-5 o? Fig. 3; F' 6 is a sectional view on the line 6 6 of i. 3; Fi 7 is a. sectional view on the line 47 of ig. 10, showing the structure of one of the upper corner brackets when wooden rails are used; Fi 8 is a sectional view showing the guide an weather strip devices on two adjacent sashes (when wooden rails are used) at respective sidesV of the window post of the car; Fig. 9 is a se arate `face view of the xed finger lift pate; lig. 10 is a face view, partly broken away, and Fig. 11 is an edge view partly broken away, showing the application of my improvements in a sash havin wooden rails; Fig. 12 is a sectional view irough a' window post and the metal rails of two sashes; Fig. 13 is a sectional view Vthrou h the metal base rail and the window si Fig. 14 is a. erspective view, partly in section of one o the metal rails of the sash and Fig. 15 is a sectional view showing the upper metal rail of alower sash and the lower metal rail of an upper sash.

1 represents a sash comprising side rails 2, bottom and top rails 3, 4 and corner brackets 5, 6.. In the embodiment of my invention shown m Figs. 1 and 2, the rails a8 Wll aS the corner brackets are made of metal, and are constructed and united in .a manner which will presently be explained. The two upper corner brackets 5, are the same in construction, as are also the several rails, but the lower right hand corner bracket embodies certain additional structural features to adapt it for the accommodation of loc and lifting devices, and the lower left han corner bracket may also be adapted for the reception of lifting means.

Each corner bracket is made of metal, preferabl aluminum, and cast hollow, forming cham rs in which cork or other insulatmg material 7 may be packed. The members 8-9 of each corner bracket are disposed at. right angles to Veach other and each of said membels is made with integral parallel plates or extensions 10 for the accommodation of the metal sash rails, the latter being adapted to be made to engage seats 11-12 formed on the respective members of the bracket between the parallel plates or extensions thereof. These seats 11-'12 may be made with openings to permit the insertion of insulating filling 7 and said openings ma bc closed by suitable plastic material as indicated at 13. The respective plates or extensions of each corner bracket member are provided with inwardly projecting lugs 14 having beveled front and rear ends, and the end oi a hollow metal sash rail'enterin between said plates or extensions is forme with recesses 15, 15, to receive said lugs, such recessed portions of the rail being connected by a web 1G. Those portions of the plates or extensions 10 having the lugs 14, are perforated for the passage of screws 17 which also pass through suitable holes in the. web 16, and in this manner themetal rails are secured to the metal corner pieces. It will be' observed that as the ln 14 on the bracket plates or extensions an the recessesll in the rails have beveled coacting walls, the rail ends will be urged to their seats in the corner brackets when the screws 17 are tightened.

Each hollow rail section is provided at one edge with a glass-retaining lip or Bange 18, carved in cross section as clearl shown in Fig. 14, und the inner edge o the respcclive members of each corner bracket are provided with Bange or lip sections 19-20, the flanges or lips 18 of the rails being recessed to receive the flange or l1 sections 20 on the corner brackets. Thus 1t will be seen that the flanges or lips 18 of this rails interlock with the alning glass-retaining flanges or lips on the corner brackets.

.Each metal rail member (2, 3, 4) 1s as fore stated, made hollow and may contain suitable insulating acking 21 as shown in Figs. 12 and 13, said rail section also having a longitudinal opening 22 for the accommodation of the face portion of a wooden nailing strip 23, the latter located within the rail section and exten from end to end thereof. The strip is glisposed diagonally within the rail section, and is retained in place by means of .slotted webs 24 located at intcrvalswith said rail section andinwhichsaldstn isseated,as clearly shown in Figs. 12 an 13. Wooden retaining strips 25am locatedon the rails and are secured in place by suitable festem ing devices 26 (either nails or screws), which pass through said strips and enter the strips 2li-said wooden strips 25 oooperating with the lips or flanges 18 on the rail and the lips or anges on corner brackets to retain the lass pane 27 in place.

The upper horizon m14 and the upper corner bracket 5 of the sash are depressed or receed in the manner indicated at 5 in Figs. 2 and 5, and in these depressed parts of the rail and corner brackets s thm plate 28 (preferably of sheet metal) is secured, said metal plate being curled at its respective edges, as at 29, to-retain the respectiye edges of a helping or bowed weather strip 30 of rubber, elt or other suitable einble material. When two sashes are employed, as shown in Fig. l5, the bowed weather strip 30 will engage the inner face of the lower rail of the upper sash and be forced u wardly and inwardly, as .in

ig. 15, and thus ellect an airtight joint between the two sashes t The bottom edge of the lower sash rail 3 1s inclined to y the inclined face .of the sill 81, and 'said lower edge of the rail ma bemcessedstw (Fig. l8)to receive a fold weather stri 88 secured to the s11l and window frame, y means of fastening means 84.'

Weatherstri Vmiarealsoraecui'edtotlie vertical rails o the sash and when the sash is in lace in the window frame, these strips 35 lbe foldedto U-shape, the folded being by a flange or rib 86 on t e rail, as own in Fig. 12. The weather strip 35 is held in place by s metal molding or retaining stri 37, said metal striplying against tbeiiwe of the weather stri and is securedtotherailbyscrews88. eed; f 1 s fr. .1 se ses. approxims y to e o s weather strip, so that said folded will belocatedbetweenoneedgsdthc 'p37 and thellaugeorriboitherail. The molding or retaini drip 37 proecta out from between the fo ds of the weather strip 37 and is formed with a shoulder 39 projectf ing toward the plane ofthe free member of the weather stri and with an extension 40 which einnerfaceof theraihss shown in ig. 12.

The weather strips 35 on ad'accnt sashes form cushions between said es and slide or uide brackets 41 secured to the T-bsr win owpost42ofthecarandthustakeup play of the saches and form weathevtight joints. It will be observed that the web and anges of the T-post are srlnewhat ta as shown in Fi. 12 andas posts o such shape do not o themselvls form desirable runways for the sashes, and hence the slides or guides 41 constitute valuable features to insure eicient guides. Each slide or guide 4l comprises a sheet of metal having a 48 bent u n itself and securely riveclznal at4:4,to ewcbofthewindowpostsousto form a smooth and ilat surface against which the flexible strip 35 may slide. From the outer portion of the 43 the metal of u? de 51mg?? ht-ally signa me o e flanges o post as at an is provided with an outwardly rejecting rib 46 to engagelthe inner facs o the flange of the post-and thus cause the lateral member 45oftheguidesheettobedisposedina plane at right angles to the transverse axis of the post and parallel with the outer face of the adjacent sash rail 2 so that the latter may have a dat outer sli relatively to the window post.- e guide sheet or bracket 41 is formed at its free edge with a loop 47 which embraces the free edge of the window post flange and the free edge of this loop portion enixiges the 'outer face of said post flange. us it will be seen that the rib 46 serves an additional function, when coperating with the loop 47, to giphor clamp the guide sheet te the flange o e T post. Instead of' the rails of the sash of metal, as herein one described they may bernadsofwoodssahownatinligs. 7 8, 10 and 11. When wooden rails are emplayed, the corner brackets may be providedr with wooden fillers 49 to which yportions of the vertical weither strips 35 may be secured 'by means of wood screws 35", the mman of said weather strips being totheouter voftliewsoden ramasshowninFig. ,10and11. The fillers 49 also serve es means to which poi` tiolnzicftheweather-stripsmaybesecu .The right hand corner bracket 6 is formed withi a pocket 50, in which a removable backing 51 of cork or other suitable material may be located. .hornear the top of the pocket 50, the end wills of the latter' an made with ves 52 to receive the ends of a n r li plate 53, said plate being inserte into the pocket so that its inner will bear against the cork backing 51. e projecting portion of the lift plate is made with shoul ers 54-55 (Fig. 9) which rest against the outer face of the corner bracket.

Above the pocketed portion of the corner bracket 6, the latter is made with a bore 56, in which the shank 57 of a. sash lock or presser foot 58 is mounted, and the end face of the bracket 6 is made with a recess 59 to receive said lock or presser foot-said recess being open at one side to rmit the lock or presser foot to reach e window frame or a suitable engaging device there on. The shank 57 of the presser foot is provided with a shaft 60 which extends through the bore 56 and is revolubly mounted in s. smaller bore 61 in the corner bracket. A. coiled spring 62 encircles the shaft 60 and one end of this spring is into a socket 63 in the shank 57,-the other end of said spring being made with a straight portion 64 (Fig. 1) to enter a groove 65 ign 2) in the wall of bore 56. The corner bracket 6 is made with a pocket 66 immediately over the pocket 50 and the finger lift. 53, for the accommodation of a finger lever 67, the latter being made with a sleeve 68 through which the presser foot shaft 60 passes, as shown in Figs. 3 and 6. The sleeve portion of the finger lever is secured to the shaft 60 by means of a screw 69, and to permit ready access to this screw after the parts shall have been assembled, the finger lift plate 53 is made with a hole 70 and the wall of the bore 56 is cut away as shown at 71.

I do not claim in this case the n ovel features of the sash lock and its monntings in the corner bracket, nor the slide or guide devices on the window post and the coperation of the sashes therewith, as these features constitute the subjects matter of separate aplications filed simultaneously herewith and designated by Serial Nos. 106,408 and 106 409. 0
